I have a question on the worth of some baseball cards. Denny Martinez two of him, Scott Stahoviak, and others.?

The other players are Jimmy Gonzalez ( I have two of him), Steve Whitaker, Jeff Reardon, Tyrone Hill, Ivan Rodriguez, Ron Grant, John Davis, Kevin Elster, Rob Ducey,Reggie Jackson, Reggie Jackson, Eric Davis, Barry Bonds (when playing for the Pirates), Pete Stanicek ( I have two of him), Jeff Treadway, Wilson Alvarez, Bernard Gilkey, Javier Ortiz, Chito Martinez, Dwight Gooden, and that is just to name a few. Anyone who can say if these are worth anything and what would be a good price to sell them.
